PETER VELANDER, OF SAN FRANCISCO, CALIFORNIA, ASSIGNOR OF ONE- HALF TO MARTIN A. BROlVN, OF SAME PLACE.

VENTILATOR FOR BOOTS OR SHOES.

SPECIFICATION forming part of Letters Patent No. 418,966, dated January '7', 1890.

Application filed July 26, 1889.

To aZZ whom it may concern:

Be it known that 1, PETER WELANDER, of San Francisco, in the countyof San Francisco and State of California, have invented a new and useful Ventilator for Boots or Shoes, of which the following is a full, clear, and exact description.

My invention relates to an improvement in ventilators for boots or shoes, the object of which is to provide a simple and convenient device whereby the thorough ventilation of the interior of a shoe or boot while in use may be effected.

A further object is to provide a ventilator for boots or shoes which may be readily secured in place at any desired point andwhich is adapted to be set in an open or in a closed position.

With these objects in view my invention consists in the construction of parts and in the combination of these parts, as will be hereinafter set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a perspective view of a portion of a shoe, showing theimproved ventilator in position thereon. Fig. 2 represents an enlarged rear face View of the preferred form of ventilator. Fig. 3 is an enlarged view in transverse sectionof the shoe or boot ventilator, taken on the line 00 as, Fig. 2. Fig. 4 is a front face View of the device. Fig. 5 is a side view in section of a modified form of the ventilator-shell and attached parts, and Fig. 6 is a side view of the modified ventilatorshell in position with its securing-edge turned over upon the shoe material.

A represents a short tubular shell of sheet metal, having a flange a turned over outwardly upon one end. The opposite end of the shell is closed by an integral plate I), as shown in Fig. 3, said plate being perforated at spaced intervals for the purpose of ventilation. Any suitable number of orifices 0 may be made in the end plate b. Four are shown in' the drawings, which are an equal distance from the center and apart from each Serial No. 318,784- (No model.)

other. The center of the end plate is also perforated, fora purpose which will be explained.

\Vithin the shell A there is located a screen cl, made of wire cloth, and upon this screen a circular piece or disk of leather 6 is imposed, said leather disk beingperforated to register its holes with those made in the end plate I). A circular cap-plate g is provided, which corresponds in its diameter to that of the shell A, which cap-plate is placed upon the leather disk 6. The cap-plate is perforated, as shown, a number of holes being made therein,which are intended to correspond with the similar sized orifices formed in the disk e and end plate I), before mentioned, and a central squared hole is also made in it.

A fine screw-thread is produced upon the outer surface of the shell A, near the end plate, and upon the threaded portion of the shell an annular flange h is screwed,it being internally threaded to permit such an engagement.

The several parts of the device, as described, being assembled in the manner specified, they are held together by the insertion through the central orifices of a rivet 2', that is squared at the end which is inserted through the capplate g, and its projecting terminal being riveted upon the cap-plate at 1;, thus secures all the parts together. Upon the opposite end of the rivet 2' a thumb-piece 7c is formed, by which the cap-plate g may be rotated along with the rivet.

In Figs. 5 and 6 a somewhat difierentlyconstructed shell is shown, and, as will be seen, the cylindrical body of the same is extended beyond the end plate I), thus providing a short tubular end A the wall of which is slitted at spaced intervals.

The remaining portions of the device are constructed similarly to those previously described, and are held in place by the rivet i and thumb-piece k.

The ventilator may be inserted in the shoe or boot upper at any preferred place. As shown, it is affixed at one side of the quarter at a point just above the arch of the sole.

When the device in its preferred form is to be attached to a shoe or boot, the flange. h is removed from the shell A, and the latter is 'aiforded.

It is evident that the insert-ion of the ventilator-shell A should be from the inside surface of the upper-leather outwardly, so as to. locate the thumb-piece of the rivet 1' upon the outside of the boot or shoe.

The shell shown in Figs. 5 and 6 of the drawingsis secured in place on ashoe or boot upper by first insertingit through a close-fitting orifice, and then bending outwardly upon the exterior surface of the upper-leather the slitted wall of the projecting tubular end A, which, when firmly seated, will retain theventilator in place. It is practical to dispense with the slitting of the tubular end A, and by means of a simple machine, similar to an eyelet-setting tool, this end may be turned over outwardly upon the upper-leather, and so secure the device in place thereon.

In use the ventilator may be left open to T afford ingress for air to the interior of the boot or shoe, and thus cool the feet of the wearer. The screens which are inserted within the shells of the device admit air and prevent sand, small stones, or other objectionable matter from entering the ventilator-holes.

In Wet weather the cap-plates are revolved sufficiently to cover the air-inlet holes, and thus sea-l them to exclude water, as the obvious use of the ventilator is to afford ventilation in hot dry weather,when the feet are liable to be blistered from their hot exhalations and sweating induced thereby.

Having thus fully described my inven tion, I claim as new and desire to secure by Letters Patent 1. In a ventilator for boots or shoes, the combination, with a cylindrical shell having an integral annular flange and a perforated end plate, of a screen, a leather disk, and a cap-plate, all perforated to align with the apertures in the end plate, a rivet having a thumb-piece, on which rivet the cap-plate may be rotated, and a ring threaded on said shell opposite its flange, substantially as set forth.

2. A ventilator for boots or shoes, consisting of a cylindrical shell exteriorlyscrewthreaded at its outer end, fixed and movable apertured disks within said shell, a threaded ring screwed upon the outer end ofsaid shell, I

and a rivet passed through said disks, having a thumb-piece on its outer end, substantially as shown and described.

1 PETER- \VELANDER.
